Followers of the outspoken groups Revolution Muslim and the Islamic Thinkers Society are moving from ideology to violent action, a review of recent terror indictments by the Investigative Project on Terrorism shows.

U.S. counter terror agencies have traditionally paid little attention to those groups, presumably because they represent a safe and legal outlet for the frustrations of young, aspiring Jihadists. Similarly, Islamist groups like the Council on American-Islamic Relations (CAIR) have minimized the danger of these individuals. CAIR spokesman Ibrahim Hooper wrote off the RevolutionMuslim.com site as "an extreme fringe group that has absolutely no credibility within the Muslim community." "In fact, most Muslims suspect they were set up only to make Muslims look bad," Hooper added. "We just have very deep suspicions. They say such outrageous, irresponsible things that it almost seems like they're doing it to smear Islam." But the new indictments show that some overzealous participants in the groups are increasing their radical activity, resulting in the groups' heightened threat. Their influence is growing.
